On Sunday night, Paddock fired hundreds of rounds of ammo into country music festival crowds from a Las Vegas hotel balcony.

Cops are still “working to process the crime scene from the Mandalay Bay Hotel and also investigate the motives of the shooter”.

“Detectives are combing through evidence to uncover the shooter’s motives and any other pertinent information that will help shed light on the Sunday night massacre.”

Cops yesterday admitted they were not yet sure of the Vegas gunman’s motives, with Clark County Sheriff Joseph Lombardo telling reporters: “We have no idea what his belief system was – I can’t get into the mind of a psychopath.”

But while the shooter himself had no criminal background, the same reportedly cannot be said for all his family.

Paddock’s father was Benjamin Hoskins Paddock, a serial bank robber.

The bandit is understood to have wound up on the FBI’s Most Wanted list in 1969 when he escaped from prison in Texas while serving a 20-year sentence.

Paddock’s brother Eric also said he was baffled, insisting his sibling had no religious or political affiliations and was just a regular guy who liked to gamble.

Some have pointed to his “high stakes poker playing” for six-figure sums as a potential trigger.

Detectives revealed Stephen carried out tens of thousands of dollars’ worth of transactions in the hours leading up to the attack – although they would not say whether they were wins or losses.

“I have absolutely no information he lost a bunch of money”, Eric told reporters. “The casino would know that.”

It comes after horrifying video showed blood-soaked concert-goers running in terror from the Route 91 country music festival after hundreds of rounds were fired from a nearby Mandalay Bay Resort Casino balcony.

Pictures show two smashed in windows at the luxury resort from where the shooter is believed to have let off a hail of deadly gunfire.

– The shooter has been named by police as Stephen Craig Paddock, 64, who was firing from the 32nd floor of the Mandalay Bay Resort Casino, and who was found dead

– Police now believe they have found Marilou Danley, 62, a woman believed to have been the roommate of Paddock

– 22,000 people had been attending the Route 91 country music festival, listening to Jason Aldean perform when the shots rang out just after 10pm on Sunday

– US President Trump has slammed the attack as “pure evil”, urging Americans to come together in solidarity

– Flights have been delayed with terrified crowds having run for cover to the McCarran International Airport

– Among the dead include a Las Vegas Metropolitan Police Department officer who was off duty. Two on-duty officers were also injured

Over a period of more than a minute at least four separate periods of sustained gunfire, believed to be from a high-powered assault rifle, were heard as hundreds of deadly rounds were unleashed into the crowd, which included children.

The death toll in the devastating attack, which began to unfold just after 10pm on Sunday night local time, surpasses the Orlando shooting at the Pulse nightclub last year, which saw 49 people killed.

Festival-goers were seen diving for cover as bullets whizzed overhead, with traumatised witnesses claiming they saw victims hit in the head.

The bullets would have created an echo effect around the tall buildings, adding to the terror and panic with people confused as to where the gunfire was coming from.

The shooter was found dead, believed to have killed himself, on the 32nd floor of the Mandalay Bay Resort after SWAT teams stormed the hotel room.

Paddock is believed to have been a grandfather, who lived in a remote desert home in Mesquite, 80 miles north-east of Las Vegas near the Arizona state border.

He urged Americans to come together, saying: "Even the darkest space can be brightened by a single light, even the most terrible despair can be illuminated by a single ray of hope."

He added: "We pray for the day that evil is banished."

He had earlier tweeted: "My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!"

The president has ordered that flags on all public buildings be lowered to half-mast in the wake of the shooting.

After President Trump addressed the nation Carolyn Goodmanm, mayor of Las Vegas, said: "This is something that was simply outrageous, uncalled for. So many young people, parents, children, loved ones who have lost someone.

"It's a city and community that has pulled together. It's been a very traumatic time and the president gave a very beautiful message and he'll be visiting us either later today, tomorrow or weds.

Brit tourist Andy Williamson, tennis star Laura Robson and pro golfer Michael Seiden were at the concert, with the Foreign Office saying it was in contact with authorities in Las Vegas, and was "ready to help" any Brits affected.

Two unnamed witnesses were in a VIP area the furthest from the Mandalay Bay Hotel, with one saying: "It was clip after clip after clip, bullets were flying everywhere, everybody running. It was really, really bad.

"We were the furthest VIP stage away from Mandalay Bay and they were ricocheting everywhere where we were.

"They were firing from somewhere high and they were unloading clip after clip after clip.”

He said: "Everyone is still running scared. The back streets are all full of people trying to hide out.

"It sounded like a firecracker then it ended up not sounding like a firecracker at all.”

Asked if they had seen any casualties, a woman with him said: “We just saw one drive by right now getting CPR.

"There were bullets ricocheting down by our feet because we all got down on the floor, crawling out, rushing out.

"I thought it was technical, like something wrong with the stage, and then it started happening again and that’s when everyone started rushing out."

Eyewitness describes the horror of Route 91 festival as Stephen Paddock opened fire on the crowd in Las Vegas

A festival-goer described the terrifying moment she saw fellow music fans falling to the ground, with Diane Navarro saying: "We were confused – we thought it might be a kid playing or fireworks.

"But then we saw people bleeding and that's when it all hit us and we all got scared. One lady was just laying there bleeding not moving.

"We didn't know if it was safe to run or stay. But my husband and I started to walk fast away from the stage and we started to see people all around us bleeding crying falling. It was unreal."

Diane, from California, said beer sellers hid behind their stalls as the shots rang out, saying: "We ran to our room and helped people come into our room. We still have one couple here they didn't want to leave.

"One man was so scared for his friends' safety he was vomiting all over the place. I'm still shaking."

Brit Nathan Judah has described being caught up in the panic following the shooting.

The journalist, from the West Midlands, was leaving the MGM Grand Las Vegas after a meal when he heard a commotion from outside on the Strip.

He said: "We were around 50 yards away from where it happened.

"It's hard to work out what we heard, but all of a sudden there was sheer panic, everyone was running away.

"We ran with them, people around us were looking for cover, trying to get to their hotels. It was pandemonium.

"We were lucky to get a taxi when we did before more crowds of people came along.

"There are people being treated in the lobby and we're looking after someone in our hotel room.

"I'm looking outside and see the area is in lockdown, police cars are everywhere.

"People are in shock, trying to call family, trying to find out what is going on."
